The Movable Do Disc allows you to understand and practice any melody or harmony in any key, by visualizing the relationships of the diatonic and chromatic tones, through any octave. It is also very suitable for sequenced learning, as the backside is printed with colours, but shows no tones, allowing you to fill in each newly learned tone until all the relative tones, diatonic and chromatic, are mastered.

Singing on solfège syllables, while pointing or simply looking at the MDD optimizes the learning experience, through a combination of conscious singing, movement and visual awareness. You can sing a song you know, practice scales, or improvise any melody you can think of. For singers, it is like having an external instrument! And above all, it is a lot of fun!


This simplified image shows the diatonic scale, with C on do (no sharps or flats). The tonal center might be any tone of the scale in its respective mode, but if the tonality is major, C would indeed be the tonic. In our la-based minor, la is the tonic, so in that case the (minor) tonic would be A.

To gain fluency in reading from the MDD, a practice sheet to practice keys up to three flats or sharps is included in the basic study kit!


Working with the Absolute Pitch Attachment is the ultimate preparation for understanding music written in staff notation and for instrumental performance of composed or improvised music. Taking up the instrument after fully grasping what will be played in sound, tonal context and absolute pitch makes confident and successful performance close to inevitable! Even if you’re singing on absolute pitch names, the APA´s transparency makes sure that the diatonic or chromatic functions of the absolute pitches are always absolutely clear.
